[John O'Duinn [:joduinn] (please use "needinfo?" flag)]

Please buy 400 of:

panda ES boards:
http://www.digikey.com/product-highlights/us/en/texas-instruments-pandaboard/686#tabs-2

(Note: there is no need to buy separate power supplies, as these will be provided as part of the chassis.)

SanDisk Extreme Pro 16gb SDSDXPA-016G-X46 SD cards X46:

For reference the last orders we did were: bug#754362, bug#769732, bug#725846 and bug#731694.



Note: per yesterday's planning meeting, these should not be delivered to SF or MV offices; these should be delivered to either SCL1 or SCL3 - :dividehex (cc'd) working to confirm delivery address which is also where assembly should happen.

Note: These boards are for testing nativeFennec on Android4.0 with these boards, hence marked as blocking bug#725544. Separate work continues for testing B2G with these boards, and a separate order will be placed once that eval is completed.

We may just have 400 2GB SD cards in stock that we're trying to RMA, let me know if you guys can use them here.

urgh: just heard that we might want to get different SD cards after all. For now, please do not buy 400 SDcards. I'll meet ctalbert and sort this out. Stay tuned.

:hlangi, thanks for the offer, but 2GB is too low.... we're borderline between 8GB and 16GB.

:ctalbert just order one industrial board for eval. http://www.amazon.com/gp/product/B007DIS6TY/ref=ox_ya_os_product. Stay tuned.

The PO will need VP & CFO approval. 

What I will need from all of you to help this process is data and a plan, including a short executive summary (the narrative).  

The types of questions I have to answer are:
* Business Unit / Purpose
* Why do we need this?
* What are we purchasing?
* What is the risk of not purchasing it?
* What is the alternative?  How did we decide to go with this recommendation?

I've also learned that any capacity planning and forecasting helps (graphs).

[matthew zeier [:mrz]]

I was only looking at the cost of the boards.  The whole system cost is over $140,000 and will also require CEO approval.

Comment 6

[John O'Duinn [:joduinn] (please use "needinfo?" flag)]

Additional info.

More info:
* Business Unit / Purpose: Release Engineering

* Why do we need this? 
We do a lot of builds and test for every checkin. More details at http://oduinn.com/blog/2012/08/21/137-hours-compute-hours-every-6-minutes/ and http://oduinn.com/blog/2012/09/04/infrastructure-load-for-august-2012/.  Until now, we've not been able to test Fennec on Android4.0. Now that we have a scalable process that works reliably , we need these boards to start providing Android4.0 coverage. 

* What are we purchasing?
400 panda boards, sdcards. Additionally, we need chassis, racks, to host these boards
Based on initial timings, we find these panda boards are comparable to existing tegra boards. We therefore estimate that 400 should be enough to handle current capacity, based on results from our ~290 tegra boards (which provide Android 2.x test coverage). Its hard to predict future checkin load, so we'll have a better idea of whether this is enough after we have these Panda running in production.

* What is the risk of not purchasing it? No Android 4.0 coverage.

* What is the alternative?  How did we decide to go with this recommendation?
Alternatives unknown. Earlier experiments w/beagle, tegras were unsuccessful. We've not yet found a board that can be used to test android4.0 at scale. Over the last months, this has been discussed at length with devs (damons, mfinkle, blassey) ateam (ctalbert), releasecoordinators (akeybl). This is the best option we know of.

joduinn any updates on the SD card situation?

Comment 9

[matthew zeier [:mrz]]

These folks move fast.  All 400 ship to Vantage tonight.  Finance has the credit app.  I'll wait until that is wrapped up before pushing for the other 400.

John owes an update on the SD cards.  Should have that today.

ctalbert did get delivery of one "industrial SD card" today, but mid-afternoon today was still wrestling with weird boot/image problems. If he cant get this resolved soon (today or early tmrw), we'll abort and go with the sd cards we know *do* work, just to unblock things for now, and revisit these "industrial" SD cards later.

Followup: met w/ctalbert, moconnor just now. 

1) The industrial card is still not usable, so lets not block on this. Investigations will continue in bug#799303, and if we get these to work, we can switch over later.

2) For now, lets go ahead with buying 850 SDcards specified in comment#0, which we know work. We'll need at least 800 (for the two batches of 400 pandas), plus should probably get some spares. We've no fail rate data for the cards, so I'll swag 50 spares for now.
